CAR-COUPLING.

SPECIFICATION forming part of Letters Patent No. 648,397, dated May 1,1900. Application filed m 8,1899. Serial No. 723,179. on, model.

To all whom it may concern.-

Be itknown that 1, JOHN BAXTER EAvns, of Forest City, in the county ofRutherford and State of North Carolina, have invented a new and ImprovedCar-Couplin g, of which the following is a specification.

My invention is an improvement in that class of automatic car-couplingsin which the coupling device proper is locked by means of a block or jawpivoted within a chamber or recess in the coupling-head or draw-bar andadapted to swing vertically for engaging or releasing said couplingdevice.

The invention is more particularly an improvement upon the coupling forwhich I have obtained Letters Patent of the United States, No. 598,500,dated February 8, 1898.

The construction, arrangement, and combination of parts are ashereinafter described, reference being had to the accompanying drawings,in which- Figure 1 is a perspective view showing a draw-head of myimproved coupling applied to a car. Fig. 2 is anenlarged centrallongitudinal section of a draw-head,showing the link supported'inposition to engage another draw-head. Fig. 3 is a cross-section on line3 3 of Fig. 2. Fig. 4 is a perspective view of the hinged block or jaw.Fig. 5 is aperspective view of the draw-head,a portion being brokenaway.

The iron draw-head or draw-bar 1 is arranged and supported beneath a carA in the usual way. It is constructed solid or integral and providedwith a flaring or conical mouth 2 and with a recess 3 (see Fig. 5) inits upper side for reception of the hinged block or jaw 4. The latter ispivoted at its front end by means of a transverse bolt 5, and said endis also rounded or constructed upon the arc of a circle which fits andseats in a like-shaped cavity in the front end of the aforesaid recess3. able pin 6, which passes vertically through it and when the jaw isclosed projects below it, as shown in Figs. 2 and 3, and enters a cavity7, formed at the inner end of the conical mouth 2 and extending belowthe same. This pin 6 engages the slotted link 8 when the latter entersthe draw-head l--that is to say, as the link 8 enters the conical mouth3 it strikes against the projecting lower end of The jaw 4 is providedwith a removthe pin 6 and thus raises the jaw 4, as shown by dottedlines, 111g. 2, and passes beyond the" pin 6 enters the slot in the link8, thereby automatically locking the latter and com pleting the couplingoperation.

To uncouple, it is obviously requisite to raise the jaw 4 to theposition shown by dotted lines, Fig. 2, which may be effected by anysuitable means.

As shown in Fig. 4, the under side of the block or jaw 4 is providedwith a broad lengthwise channel or groove 11, which coincides with asimilar channel 12in the bottom of the recess 3 of the draw-head. Thepassage thus formed by the coincident channels 11 and 12 serves to guidethe link 8 when entering the draw-head and to hold it in due alinementwith the latter, as shown in Figs. 1 and 2, when coupling is to beeffected.

In case cars are of different heights a bent link may be employed. Thepin 6 may be removed and replaced by another in case of injury. The pinsusedwith ordinary slotted link-and-pin couplings may be employed. Thusmy coupling is adapted to utilize such pins and links, sothat aconsiderable economy may be effected.

The pivot rod or bolt 5 fits somewhat loosely in the transverse bore ofthe jaw 4, so that the latter has sufficient play to allow the circularhead of the jaw to seat firmly against the adjacent portion of thedraw-head. Hence when draft is applied through the medium of the link 8the strain is borne by the solid draw-head and not by the pivot.

WVhen the jaw 8 is raised, the shoulder of the draw-head prevents itbeing thrown beyond an angle of about forty-five degrees. When closed,it lies flush with the top of the draw-head and fills the recess in thelatter 'quite accurately, so that dust and cinders are The draw-head 1may be chambered in-rear of the jaw-recess 3 for the purpose of reducingthe weight of the same. I I

My coupling is distinguished by simplicity, strength, durability, thesmall number of parts, and cheapness of construction, as well as byadaptation forautomatic coupling and easy uncoupling. What Iclaim isv 1. Ina car-coupling, the combination with the draw-head having, in itsupper side, arecess which is rounded at the front end, and a channel inits lower side, of the jaw pivoted in said recess and having a channelin its under side, which coincides with that in: the head and thus formsa passageadapted to receive and inclose the link, and the coupling-pinheld in said jaw and projecting be it into the said cavity, the adjacentor meet ing portion of the jaw and bottom of the recess in draw-headhaving coincident channels 11 and 12, as shown and described, for thepurpose specified. I

3. A car 'v coupling substantially as described comprising the draw-headhaving a flaring mouth and in rear thereof a recess for the jaw, suchrecess being provided in its lower wall with a longitudinal channel ofless width than the recess and arrangedin line with the flaring mouth,and the jaw operat ing within said recess, such jaw being arranged atits lower side to overlap and ex tend laterally beyond the channel inthe draw-head and being provided in its said lower side with a channelcoinciding with thatin the draw-head, the coupling-pin carried by saidjaw andprojecting below it, and a coupling-link-lying partly in thechannel in the draw-head and partly in that of'th'e jaw and beingsecured by said jaw, substantially asset forth.
